POST /v1/gas-oracle
method-gated
Current Base gas in one call: the live gas price, the current base fee, the base-fee range across the last 20 blocks, whether fees are rising, falling, or flat, and a cheap-window hint drawn from that data. Use this when an agent wants to time a transaction instead of paying whatever the moment charges.
Verdict: not verified by an unpaid GET. 405/400: the 402 sits behind the declared method. This says nothing about whether the route works when called as declared.
